DUST-BAG SUPPORT.

, Application filed May 27, 1922. Serial 110. 564,125.

To all whom it may concern:

Be it known that I, Max 0. RICHARDSON, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvementsin Dust-Bag Supports, of which the following is a specification.

The object. of my invention is to provide a dust-bag for portable vacuum cleaners having improved means for suspending the bag from the handle.

In these dust-bags, as formerly made, an example of which is shown in Patent No. 1,380,907, the loop by which they are attached to the handle, has been attached. to the center of the bag-head. A dust-bag of such construction has several inherent disadvantages in that, when the bag is not inflat'ed and the handle is in operative position, the bag crumples badly and sags down on the floor, thus causing undue wear on the bag at points where it falls in folds and where it contacts with the floor.

These difliculties are'caused bv the fact that t'o suspend the bag from the center of its head necessitates the use of a suspensionloop of a length equal to the radius of the bag so that when the bag is inflated it may hang freely below the handle; The effect of this is that when the bag is deflated the suspended length isthe length of the bag plus the length of the loop and it is this excessive length which? causes the crumpling and sag 'ng mentioned above.

I attain the object of my invention by the structure illustrated in the accompanying drawing in which- Figure 1 shows an inflated bag having my improved strap suspension, the handle being in operative position. and Figure 2 is a deflated bag having my improved strap-suspension, the handle being in inoperative position.

Similar reference numerals refer to similar parts in 'the two figures.

My' invention consists of a dust-bag 1 formed as shown, having side-Walls 2 and a head 3. The suspension-member 4 is attached-not as a loop but as a strap, that is, one end is. attachcd adjacentto the center of the ba head at 5, and the other end is secured a jacent the periphery of the head at 6 on the side nearest thehandle.

its ends and on the under The lower end of the bag is provided with a bag-rin 7 which is adapted to be removably atta ied to the discharge opening of a suction-cleaner 8 by means of thumb-nuts 9. A handle 10 is pivotally attached to the cleaner 8 at 11 and is provided intermediate side with a bag slider-bar 12.

Means for suspending the upper end of bag 1 from the slider-bar 12 is provided comprising a member 13 formed at one end with a closed ring which is received on the slider-bar 12 and is adapted to move freely along the length thereof. The other end is provided with a substantially-closed rin in which the bag suspension-member 4 is s idably received.

Thus a construction is secured in which when the bag is deflated, the handle being in operative position, it will be prevented from sa ging as with the old form since the bag wil? be suspended from about the point where the strap is attached to the periphery of the head. It is to be noted that this construction does not interfere with the movement of the handle to an inoperative or substantially-vertical position, since during such movement. the strap slides through the substantially-closed ring portion of member 0nd; as a means of bag suspension from approximately the center of the bag-head when the bag is deflated and the handle is in inoperative position; substantially vertical.

I claim:

1. In a dust-collecting bag having a head, a slider strap secured to the bag head, the ends of the strap being secured in spaced relation substantially diametrically of the bag head, the central portion of the strap being free.

2. In combination with a dust-collecting bag having a head, a strap secured to the head thereof, one end of the strap being secured at substantially the center of the head, the other end being secured substantially at the periphery thereof.

3. In combination with a dust-bag, a suspensi0nslider strap. the ends thereof being attached to the bag in spaced relation.

4. A. dust bag having sidewalls and a head, a single means having its ends secured to the bag head in spaced relation whereby the bag may be suspended from a point ad- 1 jacent the periphery of said head or from another point of said head.
